The code will log: B C. The switch statement compares 2 with each case. It matches case 2, so it executes console.log('B'). However, there's no break statement after this case, so execution falls through to case 3, and console.log('C') is also executed. The break statement after case 3 then causes the switch statement to exit before reaching the default case. This demonstrates the fall-through behavior of switch statements in JavaScript, which can be either a powerful feature or a source of bugs if not used carefully.
